Having an issue with office 365 and outlook 2016. This user has had his email setup on outlook 2016 on another PC previously. Purchase a new pc, downloaded office home and business 2016 from office 365 subscription. Started outlook and entered the email, error message was "something went wrong and outlook couldn’t set up your account. please try again. if the problem continues, contact your email administrator." Setup in mail app manually and got prompted for credentials. Re-entered the credentials and press OK and it keeps asking for credentials. Got a hold of Microsoft support and they walked me through removing everything manually that was office 2016 related on the PC including registry entries and re-installed office again, and still had the same issue afterwards. Also this is on windows 10 home.

Jason, thanks for posting this - I had one user having the same problem and the only thing that fixed it was clearing out all of the old Office 365 stored credentials in the Windows Credential Manager.

Disabling IPV6 did not work for me, but I have found the resolution. Under the Account Settings sub-menu, select 'Manage Profiles' instead of 'Account Settings'. You then get a Mail Setup window which is of the format of the earlier versions of Outlook. Just select 'E-Mail Accounts' and you can set up a new account just like you used to in earlier versions of Outlook. It worked for me 1st time. Hope this helps...I spent several hours searching forums and trying different things before I found this.

MY problem is that I had an office 365 account set up, the admins have done a migration and thanks to microsoft's robust design, i had to delete and try re-setup my account again. Upon setting up my account I get the same error.

All non essential protocals have already been disabled. I suspect DNS issues or firewalling or maybe something as sinister as all that.

I have been struggling with this same issue for many weeks and I found my solution.

Symptom: Can't setup outlook 2016 to get my office365 email. I get the "something went wrong message." This problem occurred on several computers with office 2016 on different networks and operating systems. However, office365 works fine from webmail, iPhone, android, and previous versions of outlook. So WTF!

I discovered that outlook 2016 is quite grumpy and so you must follow NEW protocol.

1. Uninstall all older versions of office and reboot.

2. In Control Panel, Mail (Outlook 2016), delete all profiles and close it.

3. Don't use the Mail(Outlook 2016) in control panel to setup the new account, it will not work.

4. You must use the Outlook setup wizard that will start when you open outlook for the first time with no profiles. Insert email address and password.

5. That's it.

Note: Having worked with Exchange and outlook for a very long time I find that this change was not intuitive and does not comply with standard processes maintained by Microsoft for a decade. You should be able to use the Mail control panel tool to set this up as we have always done. I find that this is definitely a bug in Outlook 2016. I hope this helps others that were just a frustrated as me.

Further to this, I have solved my issue by remove all outlook credentials in windows credential manager. Due to migration, the account is the same and windows in all it's wisdom keeps trying to connect to the new account with the old account credentials. The account ID is different with the new account (auto generated?)

After deleting all credentials, I was able to add the account within seconds.

My resolution was simpler but far from obvious...

When it offers you the option to "Change Account Type" (if I remember correctly), click "Google" instead of 365. This takes you to a dialog box where you can manually configure servers, ports, etc. Just accept the defaults then enter your Office 365 password when prompted. That got my Office 365 account up and running in Outlook.

It's a pretty straightforward approach - simply take the default configuration options (as they already reflect appropriate Office 365 Server and Port settings) and insert your password when prompted. I can speculate as to WHY this works, but all that matters - I didn't have to overhaul my Windows 10 to find out it's an Outlook 2016 issue. Microsoft - please fine tune the setup of 365 Exchange services with the preferred/recommended Microsoft Mail Client.

Thank you!!!! This solved my issue. The solution above is a good one for the many issues profiles have in outlook and the search function, but this one was much different than that and just didn't make sense to me.
